Shall I not in that day, saith the LORD, even destroy the wise men out of Edom, and understanding out of the mount of Esau?
Shall I not ... saith the Lord, even destroy the wise men out of Edom (Jeremiah 49:7: cf. Job 5:12-13; Isaiah 19:3; Jeremiah 19:7).
In that day ... even destroy - heretofore Edom, through its contact with Babylon and Egypt, and from its means of information through the many caravans passing to and fro between Europe and India, has been famed for knowledge; but "in that day" at last, and in particular ("even") I will destroy its wise men.
Out of the mount of Esau - i:e., Idumea, which was a mountainous region.
